FA$TENER FOR MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 368,004, dated August 9, 1887. J

Application filed April 12, 1887. Serial No. 234,514. (No model.)

To all whom it may concern.-

Be it known that I, JOHN F. PooL, of Mount Carmel, in the county of Wabash and State of Illinois, have invented a new and Improved Window-Fastener, of which the following is a full, clear, and exact description.

The object of this invention is to provide a sash-fastener whereby the sash may be securely locked in a closed position, and whereby the sash may be held partially open, as will be hereinafter more fullyexplained,and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a view of the inner face of a window-sash provided with my improved form of fastener, the frame at the top of the windowcasing being broken away to disclose the arrangement of the catch and keeper employed to hold the upper sash in a raised position. Fig. 2 is a sectional view taken on line at w of Fig. 1; and Fig. 3 is a sectional view of aportion of the upper sash and of the fasteningcatch that is carried by the upper cross-bar of i the lower sash, the case of said catch being of the sash above its centralrail.

shown in section.

In the drawings, 10 represents the windowcasing, 11 the upper and 12 the lower sash, which sashes are provided with a heavy central rail, 13. With such sashes as those illustrated in the drawings the parts of the fastener arranged in connection with the upper sash are secured to said heavy central rail, 13,

while the parts of the fastener carried -by the lower sash are secured to the upper cross-bar However, with windows having light central rails the fastening devices would be secured to the side rails of the sash.

The fastener consists of a catch, 14, that is mounted within a case, 15, the catch being supported by a pivot-pin, 16, which carries a forwardly-extending spring, 17, said spring resting in an aperture, 18, thatis formed in the catch,and tending to hold the catch in the position in which it is shown in Fig. 3. The casing of this catch is secured to the upper cross bar of the lower sash, in position so that the point of the catch Will be in line with the centers of a series of castings, 19, that are secured to the upper sash, these castings 19 being formed with upper and lower curved arms, 2,

and with upper catch-recesses, 3, and lower catch-recesses, 4. As many of these castings may be employed'as may be deemed practicable.

To the upper cross-bar of the sash 11,1 connect a'catch, 20, that is arranged to enter a recess, 21, that is formedin the upper part of the windowcasing, the point of said catch passing through a central slot or opening that is formed in a plate, 22, arranged as illustrated in Fig. 1 of the drawings. This catch 20 is provided with a lever-arm, 23, which is held' loosely against the upper cross-bar of the sash 11 by a staple, 24., and just beyond the pivot 5, upon which the catch is mounted, I form a recess, 6.

WVhen it is desired to lock the windowsash in the closed position, the upper sash is moved upward until its catch 20 engages with the plate 22. Then the lower sash is closed and the point of the catch 14 is brought into engagement with the recess 4: of the lower casting, 19. A pin, 60, is then inserted in proper apertures formed inthe casing 15, and being so inserted will act to hold the catch in the position in which it is shown in Figs. 1 and 3- that is, to hold the point of the catch against the face of the lower arm, 2, of the lower easting.

When it is desired to raise the window, the pin is removed, the catch M is grasped by its handle or knob 7 and moved in the direc tion of the arrow, shown in Fig. 3, being in this way freed from engagement with the recess 4 of the lower casting. The'sash 12' may then be raised, and for convenience I prefer to provide said sash with a knob or handle, 28. After the sash 12 has been slightly raised the catch may be released, and the spring 17 will then force the point of the catch to bear against the convex face of the upper arm of the lower casting. As the sash is raised the point of the catch let will strike against the convex face of the lower arm of the nextcasting above, and as the upward movement of the sash continues the spring 17 will force the point of the catch into engagement with the recess 3 of the last-mentioned casting; and if at this time the hold upon the sash .12 be released it will be supported in the position to which it has been moved. When it is desired to lower the upper sash, the lower sash is raised until thepoint of the catch 14 has passed the upper casting, 19, and entered the recess 6 of the casting 20, when, if a slight upward movement is imparted to the lower sash, the catch 20 will be disengaged and the upper sash will be free to drop as the lower sash is moved downward. When it is desired to sup port the upper sash in a lowered position, the catch 1; may be brought into engagement with any one of the recesses 4. It will be noticed that the points of the arms 2 extend beyond the central lines of the castings 15), so that in moving the lower sash upward the catch 14 will freely pass all of the castings, moving at this time upon the left-hand face of the lower arm, and in lowering the upper sash the catch will pass upon the right-hand side of the upper arm.

This fastening entirely obviates the necessity of counterbalancingweights, and consequently materially eheapens the cost of hanging the sash; and it will be seen that the fastening may be applied to most any form of window without material alteration.

Although I have described the parts 19 as being castings, it will of course be understood that they might be stamped in sheet metal or otherwise formed.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a horizontallyoscillating catch and a spring for returning it to its normal position at right angles to the plane of the sash, of a vertical plate or casting recessed at top and bottom, and having arms inclined orcurved in opposite directions across the path of the free end of the catch, one of said arms projecting upwardly from one side over the recess in the top of the plate and the other downwardly from the other side below the recess in the bottom of the plate, substantially as set forth.

2. The combination, with a horizontallyoscillating catch having a longitudinal slot, and a spring secured to the catclrpivot and entering the slot to hold the catch at right angles to the plane of the sash, of the plate or casting recessed at top and bottom and having arms inclined or curved in opposite directions across the path of the free end of the catch, one of the said arms projeeti ng upwardly from one side over the recess in the top of the plate and the other downwardly from the otherside below the recess in the bottom of the plate, substantially as set forth.

3. The combination, with the fastener for the meeting-rails, of the catch for locking the top rail of the upper sash to the top of the window-casing, said catch having an arm extending into the upward. path of that part of the fastener which is on thelowersash, whereby when the lower sash is raised the said catch will be released, substantially as set forth.

4. A fastening mechanism for sashes, comprising the horizontally-oseillating meetingrail fastener having a spring holding it normally at right angles to the top rail of the lower sash, the plates or castings on a vertical rail of the upper sash inclined or curved in opposite directions on their side edges at opposite sides of their centers and recessed in their opposite sides, the angular catch pivoted to the top rail of the upper sash and having a recess in the lower edge of its horizontal arm to receive the free end of the meeting rail. fastener and in a vertical alignment with the normal position thereof", and the catchplate on the casing for the vertical arm of the catch, substantially as set forth.
